Let W be the union of the and quadrants in the​ xy-plane. That​ is, let . Complete parts a and b below. a. If u is in W and c is

any​ scalar, is cu in​ W? Why? A. If u is in​ W, then the vector cuc is in W because c0 since . B. If u is in​ W, then the vector cuc is not in W because c0 in some cases. C. If u is in​ W, then the vector cuc is in W because since . Your answer is correct. b. Find specific vectors u and v in W such that uv is not in W. This is enough to show that W is not a vector space. Two vectors in​ W, u and v​, for which uv is not in W are nothing. ​(Use a comma to separate answers as​ needed.)

The shortest side of an isosceles triangle is 2x - 3 inches long. the longer sides are 6 inches longer than the shortest side. t
Zolol [24]
Side 1 = short side = 2x-3
side 2 = longer side = (short side) + 6 = (2x-3)+6 = 2x+3
side 3 = side 2 = 2x+3

Side 2 and side 3 are the longer two congruent sides

Add up the three sides and set them equal to the given perimeter of 33. Solve for x

(side1)+(side2)+(side3) = perimeter
(2x-3)+(2x+3)+(2x+3) = 33
(2x+2x+2x) + (-3+3+3) = 33
6x+3 = 33
6x+3-3 = 33-3
6x = 30
6x/6 = 30/6
x = 5

If x = 5, then the longer sides are 2*x+3 = 2*5+3 = 10+3 = 13 inches each
(note: the short side is 2*x-3=2*5-3=10-3 = 7 inches)

Answer: 13 inches

What is the savings rate per month?
dedylja [7]

Answer:

My guess is $29

Step-by-step explanation:

So first I take the difference of the 10th and 6th month, which is 116.

I take that and divide it by 4, because that was the change in 4 months(10-6)

116÷4=29
